# NOTE: basic-pitch pins tensorflow<2.15.1 which has NO Python 3.12 wheels, and
|
|
# forcing a source build of old numpy fails on py3.12 (pkgutil.ImpImporter removed).
|
|
# So this container uses Python 3.11, where tensorflow 2.15.x + numpy 1.26.x ships
|
|
# prebuilt cp311 wheels and `pip install basic-pitch` "just works".
